In this paper, based on the finite element simulation method of supercomputer, a three-dimensional intelligent modeling analysis of energy-saving and environmentally friendly concrete materials is carried out. First, the basic principles of the finite element iterative integral equation are introduced. The various characteristics of concrete materials and the interaction between steel and concrete, through calculation, people have a more comprehensive and in-depth grasp of the properties of reinforced concrete structures. In the process of nonlinear finite element analysis of reinforced concrete, physical models, numerical methods and programming techniques are involved. The final formation of the analysis program is an important part of it. By using the balanced grid division strategy of graph partition theory and sparse matrix reordering technology, the performance and scalability of the program are improved to 97.2%
